PUMP.

SPECIFICATION forming part of Letters Patent No. 241,856, dated May 24, 1881.

Application tiled September 4, 1880. (No model.)

To all whom t may concern:

Beit known that l, JOHN J. GARDNER, of Lancaster, in the county of Jefferson and State of Indiana, have invented a new and valuable Improvement in Pumps; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the sa1ne,reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of thedrawings is a representation of a central vertical section of this invention. Fig. 2 is a transverse section. Fig. 3 is an exterior view, showing the agitating device. Figs. 4, 5, and 6 are details.

This invention has relation to single-acting pumps; and it consists in the construction and novel arrangement of the four tapering edge lapped boards forming the barrel, the valved tube let into the lower end of the same, the loose valve-block and slotted rubber cap eX- tending beyond its sides, and the perforated blocks secured to 'a reciprocating rod arranged in ways on the outside of the pumpbarrel, all as hereinafter shown and described.

In the accompanying drawings, the letter A designates the pump-barrel, which is constructed of four boards of the same size and shape, each board a being tapering slightly and usually about ten feet long, being oneeighth of an inch wider at the top than at the bottom. These boards are put together in such a manne-r that each board has one edge, b, lapping the next on one side, while on the other side its other edge, c, i's abutting against the edge of the adjacent board, so that there is one seam only on each side of the barrel, which has a square aperture, d, the top of which is one-eighth of an inch wider than the bottom portion.

Into the lower end of the barrel is inserted and secured a pipe or tube, B, squared to fit the chamber, and having an end piece, c, and inlet-openingsf on each side. Io the top of this pipe or tube B, which forms the valve-seat g, is fitted a valve, C, consisting of a fiat piece of rubber, h, having a block, 7c, nailed thereto, therubberbeingnailed byone edge to thevalveseat, thereby forming the cheokevalve of the pump.

The plunger D consists of a square block, I, cut of smaller diameter than the aperture of the barrel, so as to fit within it loosely, leaving a space between its sides and the barrelwall. A teuon, l, is formed on the Lipper end of the valve-block, projecting upward centrally between the corner holes, m, which aie made through the block for the passage of the water.

A square rubber cap, n, of dat or sheet rubber is out of sufcient size to tit the aperture of the barrel closely, and is formed with a central cross-cut, s, so that it can be pushed down over the tenon l, and will then be square with its seat on the upper surface of the valve-block I, beyond the sides of which it extends, as shown in the drawings. This cap, being elastic, clasps the tenen, and the. angular inside iiaps p are nailed to the tenon. The edges of Ithe rubber cap are designed to make an airtightjoint with the inside wall of the barrel, which is rendered closer in the lower part ot' the barrel because of its taper.

The tenon l of the valve-block forms a part of the plunger-stem E, to which it is rigidly conn'ected by halving and bolting, as shown at r.

Around the barrel, at its bottom, a metallic strap, F, is secured, holding the component boards a together more securely in this part, while at the top tie-strips t are nailed around on three sides, as shown, said strips connecting on the fourth side with the lever-support Gr, which is nailed to the side of the barrel, and is provided with a forked branch, H, which projects above it.

L represents the lever, which is pivoted to said support, and is connected to the plungerstem by means of a hook-hinge, fu. To the outer arm of this lever is pivoted the jointed or flexible end J of a reciprocating-stem, K, which works in bearin gs w, secured to the barrel-wall, and which is provided with upper and lower agitating heads or blocks, U V, which are perforated at z, and which are moved up and down in the water, outside the pump-barrel, when the plunger-lever is operated, and serve to create currents in` the water about the inlet-openings in the entrancetube B, and to prevent stagnation.

z represents the spout, secured in a board of the barrel, near its upper end.

IDO

The operation of the pump is as follows: The barrel heilig tapering from top to bottom, the plunger descends andthe space between the sides of the block I and the walls ot' the pump-barrel gradually lessens as the plunger approaches the bottom. The rubber cap n, having its edges extended beyond the sides ofthe block I, is in contact with the walls ofthe barrel, and is lifted by them and the water during its descent. The water passes through the holesm and around the sides ofthe block I, and passes the edges ot' the rubber cap a. When the plunger has reached the end of the downward stroke the upward stroke commences, and, owing to the tapering form ofthe barrel, the rubber cap a packs the barrel so tightly at this point that no leakage of the water above the cap can take place; hence a greater volume ot' water is lifted than would be were the barrel straight throughout. The rubber cap a will not rot. as does leather, and taint the water afterlong use. The block l being smaller than the inner area of the barrel, no friction has to be overcome, except that ot' the rubber cap i1, and this is so slight as not to wear the barrel; and when the cap itselt` becomes worn it can be replaced by any ordinary mechanic.

The operation of the agitator has already been explained.

Agitators for stirring the water to prevent stagnation are not broadly new, and are not so claimed herein. A wire secured to thepumprod, and having disks attached to it,has been used for this purpose; and a rod has been connected to the pump-handle and provided with a perforated stirrer or agitator at the bottom; but in both these instances no guides are used, nor are the agitators connected in any way to the famili-barrel below the water, as in my invention. By the employment of the guides the agitator will not be deected by the water, and the action ofthe pumpis made certain.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a pump, the barrel A, formed 0f four tapering boards, a, the face ot' each of which is lapped over the edge of the next, thereby forming a single seam in each side ot' the barrel, as set forth.

2. The combination of the valve a, eut, as shown at s, to form flaps 1), with the plungerblock l, stem l E, tapering barrel A, and checkvalve C, substantially as and for the purposes set forth.

3. ln a pump, the combination, with the lever L and pump-barrel A, of the reciprocating stem K, working in bearings w, aml provided with the agitating blocks or heads U V z, substantially' as and for the purposes set forth.

In testimony that I claim the above l have hereunto subscribed my name in the presence of two witnesses.

JOHN J. GARDNER.
